Chris Whelan mumbled incoherently to the rest of uk.rec.cars.maintenance:
Wouldnt make much sense, they make most of their profits off services, repairs and spares. If they all failed at once they'd be financially unviable before they could have made much profit. Ideally you keep the body looking perfect (not rotting away) and make the mechanicals fail slowly. That way people see the vehicle as worth repairing each time and spend more than if you just say "oh its all gone to pot, bin it".
